IMO word of mouth has worked well for me. Ask around, especially older(ish) people who are heavily involved in trying to retire
I know my parents have used multiple people over the years and have found someone about 5 years ago who they REALLY like. He doubled their retirement savings in 3 years. Multiple people in my family now use the guy and all are extremely pleased.
Only other option I would know of is the Dave Ramsey list of "ELP", 'Endorsed Local Provider". No clue if it means anything but I like Dave
